GLOSSARY OF TERMS
Bandwidth
The amount of information or data (text, images, video, sound)
that can be sent over a communication channel, such as a
network, in a given period of time. The higher the bandwidth,
the more information the channel can carry. It is similar to
roadways—a four-lane highway can carry more traffic than a
two-lane highway.
Blackline Masters
Supplementary materials in the form of worksheets and other
tools associated with DE
streaming video programs. They are in
PDF format so that they can be easily downloaded and printed
to hand out to students. You will need Adobe Acrobat Reader
installed on your computer to be able to open these files.
Buffer
A temporary storage location for data information being sent or
received. It compensates for differences between two different
devices in ability or speed in data handling. The buffer functions
like a reservoir, capturing the data and then letting it out at
speeds the lower-capacity device can accommodate. The verb
buffer refers to the act of collecting and storing the data until it
can be used.
Download
To transfer or save a file from a computer or server to your own
computer via the Internet. Things you might download include
video and image files. After an image or video is downloaded,
you may view the file on your own computer without being
connected to the Internet.
Embedded Video
When you embed a downloaded file, you insert it right into your
document. Embedding makes use of the multimedia capabilities
in software such as PowerPoint, AppleWorks, and Keynote and
allows teachers to create presentations that do not rely on
separate media players. Embedding is an effective way to add
video content to existing presentations, create interactive
learning projects with menus and text prompts, or develop slide
shows in which video files play automatically.
Hyperlink
A hyperlink is a text or graphic element that points to a specified
web page or opens a digital file that has been saved on a local
computer or network server. After you have downloaded and
saved DE
streaming video segments, you can create hyperlinks
using text and images. Users simply click the text or image
hyperlink to open and play a video segment. Hyperlinking is a
simple way for teachers and students to play video files within a
separate media player window that provides access to player
controls such as volume, play, pause, and stop.
PDF file
Portable Document Format. This format was developed by
Adobe to allow files to retain their original formatting regardless
of whether the end user has the program with which the file was
created. The documents will have the extension “PDF.” You
must have Adobe Acrobat Reader (a free download from the
Adobe website) installed on your computer to be able to open
the files.
Stream
Any data transmission that occurs in a continuous flow.
Streaming audio and video files allow you to display or play the
beginning before all the data has been transferred. A DE
streaming video file can be streamed and played in Windows
Media Player (PC) or QuickTime player (Mac). You can begin
viewing the file with little delay as opposed to waiting for the
entire file to download.
Teacher’s Guide
A supplementary guide is available for most DE streaming video
programs. Teacher’s Guides contain program objectives,
discussion questions, and lesson plans that support DE
streaming video content. The PDF format ensures easy
downloading.
Webinar
An online seminar with interactive training elements. Discovery
Education offers hour-long sessions using the platform WebEx
and a phone. A variety of topics and times are available each
week—all free with your DE
streaming license.
